In most living species, especially the free-swimming feather stars, the arms branch several more times, producing up to two hundred branches in total. Being jointed, the arms can curl up. They are lined, on either side alternately, by smaller jointed appendages known as "pinnules" which give them their feather-like appearance.

Leaf-like structure formed from a sepal or calyx lobe which enlarges, usually many-fold, before or after anthesis, especially when most of the other sepals or calyx lobes retain their original size. More extreme than an accrescent calyx, calycophylls are found in Rubiaceae. Compare semaphyll and pterophyll. calyculate Having an epicalyx ...

Fruits are the mature ovary of seed-bearing plants, and they include the contents of the ovary, which can be floral parts like the receptacle, involucre, calyx, and others that are fused to it. Fruits are often used to identify plant taxa, help to place the species in the correct family, or differentiate different groups within the same family.
The inner surface of the corallite is known as the calyx. The vertical blades inside the calyx are known as septa and in some species, these ridges continue outside the corallite wall as costae. [2] Where there is no corallite wall, the blades are known as septocostae.
